Abstract
Description
Technical Field
[0001] This application belongs to the field of communication technology, specifically relating to a hinge mechanism and an electronic device. Background Technology
[0002] With the development of technology, people are becoming increasingly reliant on electronic devices. In pursuit of a better visual experience, the screen sizes of electronic devices are getting larger and larger, but this has resulted in a significant reduction in the portability and user comfort of these devices.
[0003] To maintain portability and user comfort, foldable electronic devices are increasingly widely used. In related technologies, foldable electronic devices employ hinge mechanisms to achieve the folding and unfolding processes. These hinge mechanisms incorporate elastic elements, one end of which is fixed. During the folding process, the other end of the elastic element is stretched or compressed, generating an elastic force (damping force) to maintain the foldable device at a preset angle and improve user experience. However, the elastic force generated by each element is limited. Therefore, to ensure sufficient damping force, multiple elastic elements are needed, each generating its own elastic force. However, this results in a large number of elastic elements, increasing the space occupied by the hinge mechanism and hindering the miniaturization of electronic devices. Summary of the Invention
[0004] The purpose of this application is to provide a hinge mechanism and electronic device that can solve the problem of increased space occupied by hinge mechanisms in related technologies.
[0005] In a first aspect, embodiments of this application provide a hinge mechanism for rotatably connecting a first housing or a second housing of an electronic device to allow the electronic device to have an unfolded state and a folded state. The hinge mechanism includes a base, a rotating member, a first sliding member, a second sliding member, and an elastic member, wherein:
[0006] The rotating member includes a first rotating part and a second rotating part, which are arranged sequentially along the rotation axis of the rotating member. The first rotating part cooperates with the first sliding member, and the second rotating part cooperates with the second sliding member. The two ends of the elastic member are respectively connected to the first sliding member and the second sliding member.
[0007] During the switching process between the unfolded state and the folded state of the electronic device, the rotating member rotates, and the first rotating part and the second rotating part respectively drive the first sliding member and the second sliding member to move in opposite directions. The first sliding member and the second sliding member act on the elastic member at the same time, so that the elastic member undergoes elastic deformation.
[0008] Secondly, embodiments of this application also provide an electronic device, including a first housing, a second housing, and the aforementioned hinge mechanism, wherein the rotating member is connected to the first housing or the second housing.
[0009] In the embodiments of this application, when the first and second rotating parts of the rotating member rotate, the first and second sliding parts drive the two ends of the elastic member to undergo elastic deformation simultaneously. That is, both the first and second ends of the elastic member generate deformation. Compared with the scheme where one end of the elastic member is fixed and the other end generates deformation, the deformation of the elastic member is increased, and the elastic force of each elastic member, i.e., the damping force, is increased. Therefore, while ensuring that the total damping force of the hinge mechanism remains unchanged, the number of elastic members can be reduced, the number of components of the hinge mechanism is reduced, and the space occupied by the hinge mechanism is reduced, which is conducive to the miniaturization of electronic devices.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0025] The hinge mechanism and electronic device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.
[0026] Please refer to Figures 1-3 The hinge mechanism S disclosed in this application is used to rotatably connect the first housing or the second housing of the electronic device, so that the electronic device has an unfolded state and a folded state, that is, the electronic device is a foldable electronic device. The first housing and the second housing are rotated relative to each other through the hinge mechanism S, thereby realizing the folding or unfolding of the electronic device.
[0027] The hinge mechanism S includes a rotating member 100, a first sliding member 210, a second sliding member 220, and an elastic member 300. The rotating member 100 includes a first rotating part 110 and a second rotating part 120, which are arranged sequentially along the rotation axis of the rotating member 100 so that the first rotating part 110 and the second rotating part 120 rotate synchronously around the rotation axis during the rotation of the rotating member 100. Moreover, the first rotating part 110 cooperates with the first sliding member 210, and the second rotating part 120 cooperates with the second sliding member 220. Optionally, the first rotating part 110 and the first sliding member 210, and the second rotating part 120 and the second sliding member 220, can be connected by a screw transmission structure. Optionally, the first rotating part 110 and the second rotating part 120 are provided with a screw groove, and the first sliding member 210 and the second sliding member 220 can be provided with a protrusion. The protrusion cooperates with the screw groove to drive the first sliding member 210 and the second sliding member 220 to move when the first rotating part 110 and the second rotating part 120 rotate.
[0028] The two ends of the elastic element 300 are connected to the first sliding element 210 and the second sliding element 220, respectively. Optionally, the elastic element 300 may be, but is not limited to, a spring, as long as it can deform with the movement of the first sliding element 210 and the second sliding element 220.
[0029] During the switching between the unfolded and folded states of the electronic device, the rotating member 100 rotates, and the first rotating part 110 and the second rotating part 120 respectively drive the first sliding member 210 and the second sliding member 220 to move in opposite directions. The first sliding member 210 and the second sliding member 220 simultaneously act on the elastic member 300, causing the elastic member 300 to undergo elastic deformation. Optionally, the moving directions of the first sliding member 210 and the second sliding member 220 are parallel to the rotation axis of the rotating member 100.
[0030] In this embodiment, when the first rotating part 110 and the second rotating part 120 of the rotating member 100 rotate, the first sliding member 210 and the second sliding member 220 respectively drive the two ends of the elastic member 300 to undergo elastic deformation simultaneously. That is, both the first end and the second end of the elastic member 300 generate deformation. Compared with the scheme where one end of the elastic member 300 is a fixed end and the other end generates deformation, the deformation of the elastic member 300 is increased, and the elastic force of each elastic member 300, i.e., the damping force, is increased. Therefore, while ensuring that the total damping force of the hinge mechanism S remains unchanged, the number of elastic members 300 can be reduced, the number of components of the hinge mechanism S is reduced, and the space occupied by the hinge mechanism S is reduced, which is conducive to the miniaturization of electronic devices.
[0031] On the other hand, reference Figure 1As shown, since the space occupied by each hinge mechanism S is reduced, more hinge mechanisms S can be set in the same space. The sum of the damping forces of all hinge mechanisms S increases, which helps the electronic device to stay stably at the preset angle and improves the user experience.
[0032] Optionally, the hinge mechanism S may also include a base 700, which serves as the mounting base for the rotating member 100, the first sliding member 210, the second sliding member 220, and the elastic member 300, and the rotating member 100 may rotate relative to the base 700.
[0033] In one optional embodiment, the first slider 210, the first rotating part 110, the second rotating part 120, and the second slider 220 are arranged sequentially along the rotation axis of the rotating part 100. The elastic element 300 is disposed on one side of the first slider 210 and the second slider 220, that is, the first slider 210 and the second slider 220 are arranged side by side with the elastic element 300. During the switching between the unfolded state and the folded state of the electronic device, the first rotating part 110 drives the first slider 210 to move in a direction away from the second slider 220, and the second rotating part 120 drives the second slider 220 to move in a direction away from the first slider 210. The distance between the first slider 210 and the second slider 220 increases, so the elastic element 300 is stretched.
[0034] In another embodiment, the elastic element 300 is disposed between the first sliding element 210 and the second sliding element 220. That is, the first rotating part 110, the first sliding element 210, the elastic element 300, the second sliding element 220, and the second rotating part 120 are arranged sequentially along the rotation axis of the rotating part 100. During the switching between the unfolded state and the folded state of the electronic device, the first rotating part 110 drives the first sliding element 210 to move in a direction closer to the second sliding element 220, and the second rotating part 120 drives the second sliding element 220 to move in a direction closer to the first sliding element 210. The distance between the first sliding element 210 and the second sliding element 220 decreases, so the elastic element 300 is compressed. In this embodiment, the elastic element 300 is directly located between the first sliding element 210 and the second sliding element 220. The structure of the elastic element 300, the first sliding element 210, and the second sliding element 220 is more compact. Moreover, the elastic element 300, which adopts a compression deformation method, occupies less space, which is beneficial to reducing the space occupied by the hinge mechanism S.
[0035] In one optional embodiment, the hinge mechanism S may further include a support member rotatably connected to the rotating member 100. The support member may be provided with a first cylindrical groove and a second cylindrical groove. A first column is provided at the end of the first rotating part 110 away from the second rotating part 120. The first column extends into the first cylindrical groove and is rotatably engaged with the first cylindrical groove. A second column is provided at the end of the second rotating part 120 away from the first rotating part 110. The second column extends into the second cylindrical groove and is rotatably engaged with the second cylindrical groove, so that the rotating member 100 rotates stably.
[0036] In another embodiment, the hinge mechanism S further includes a rotating shaft 400, the rotation axis of the rotating member 100 is the axis of the rotating shaft 400, the elastic member 300 includes a first elastic member 310, and the first rotating part 110, the first sliding member 210, the first elastic member 310, the second sliding member 220, and the second rotating part 120 of the rotating member 100 are sequentially sleeved on the outside of the rotating shaft 400, and the first sliding member 210 and the second sliding member 220 both move along the axial direction of the rotating shaft 400. Optionally, the first rotating part 110, the second rotating part 120, the first sliding member 210, and the second sliding member 220 all include a cylindrical part, which is sleeved on the outside of the rotating shaft 400. In this embodiment, by setting the rotating shaft 400, not only can rotational support be provided for the first rotating part 110 and the second rotating part 120 to improve rotational stability, but also the moving direction of the first sliding member 210 and the second sliding member 220 and the deformation direction of the first elastic member 310 can be guided to ensure that the first sliding member 210 and the second sliding member 220 move accurately along the axial direction of the rotating shaft 400, and to make the first elastic member 310 undergo elastic deformation along the axial direction of the rotating shaft 400.
[0037] In one optional embodiment, the rotating shaft 400, the first elastic element 310, and the rotating element 100 are all configured as one.
[0038] In another embodiment, combined Figure 2 and Figure 3 As shown, the rotating shaft 400 includes a first rotating shaft 410 and a second rotating shaft 420 that are parallel to each other. The rotating component 100 includes a first rotating component 101 and a second rotating component 102. The first rotating component 101 and the second rotating component 102 are respectively connected to the first housing and the second housing of the electronic device. Both the first rotating component 101 and the second rotating component 102 include a first rotating portion 110 and a second rotating portion 120, and the first rotating component 101 and the second rotating component 102 are respectively sleeved on the first rotating shaft 410 and the second rotating shaft 420. Optionally, the first rotating portion 110 and the second rotating portion 120 of the first rotating component 101 and the second rotating component 102 both include a cylindrical portion. The cylindrical portion of the first rotating component 101 is sleeved on the outside of the first rotating shaft 410, and the cylindrical portion of the second rotating component 102 is sleeved on the outside of the second rotating shaft 420.
[0039] Furthermore, both the first slider 210 and the second slider 220 include a connected first portion 201 and a second portion 202. The first portion 201 of the first slider 210 is opposite to the first portion 201 of the second slider 220, and the second portion 202 of the first slider 210 is opposite to the second portion 202 of the second slider 220. A first elastic element 310 is provided between the first portion 201 of the first slider 210 and the first portion 201 of the second slider 220, and between the second portion 202 of the first slider 210 and the second portion 202 of the second slider 220. Thus, the sliding synchronization of the first portion 201 and the second portion 202 of the first slider 210 is high, as they simultaneously compress the first ends of the two first elastic elements 310. Similarly, the sliding synchronization of the first portion 201 and the second portion 202 of the second slider 220 is high, as they simultaneously compress the second ends of the two first elastic elements 310, maintaining a consistent degree of deformation for each first elastic element 310 and preventing the electronic device from being unable to fold or unfold stably due to different degrees of deformation.
[0040] Of course, in other embodiments, at least two first sliders 210 may be provided, wherein the two first sliders 210 respectively cooperate with the first rotating part 110 of the first rotating part 101 and the first rotating part 110 of the second rotating part 102; at least two second sliders 220 may also be provided, wherein the two second sliders 220 respectively cooperate with the second rotating part 120 of the first rotating part 101 and the second rotating part 120 of the second rotating part 102.
[0041] The first portion 201 of the first sliding member 210, the first portion 201 of the second sliding member 220, and the first elastic member 310 between them are sleeved on the outside of the first rotating shaft 410. The second portion 202 of the first sliding member 210, the second portion 202 of the second sliding member 220, and the first elastic member 310 between them are sleeved on the outside of the second rotating shaft 420. That is, the first rotating part 110 of the first rotating member 101, the first portion 201 of the first sliding member 210, the first elastic member 310, the first portion 201 of the second sliding member 220, and the second rotating part 120 of the first rotating member 101 are sequentially sleeved on the outside of the first rotating shaft 410; the first rotating part 110 of the second rotating member 102, the second portion 202 of the first sliding member 210, the first elastic member 310, the second portion 202 of the second sliding member 220, and the second rotating part 120 of the second rotating member 102 are sequentially sleeved on the outside of the second rotating shaft 420.
[0042] By providing at least two rotating parts 100, either the first housing or the second housing of the electronic device can be rotated, which improves the mobility of the electronic device. By providing at least two rotating shafts 400, each rotating part 100 can be supported, ensuring that each rotating part 100 can rotate stably. At the same time, the at least two rotating shafts 400 apply guidance to different positions of the first sliding part 210 and the second sliding part 220, which is beneficial for the first sliding part 210 and the second sliding part 220 to move accurately along the axial direction of the rotating shaft 400, and also beneficial for each first elastic part 310 to undergo elastic deformation along the axial direction of the rotating shaft 400. Furthermore, by providing at least two first elastic parts 310, the number of first elastic parts 310 increases, thereby increasing the damping force of the electronic device during state switching, which is beneficial for the electronic device to maintain a stable position at a preset angle, thus improving the user experience.
[0043] In an optional embodiment, the first portion 201 and the second portion 202 of the first slider 210 are directly connected, and the first portion 201 and the second portion 202 of the second slider 220 are also directly connected. The first elastic member 310 sleeved on the first rotating shaft 410 and the first elastic member 310 sleeved on the second rotating shaft 420 are arranged adjacent to each other. In another embodiment, both the first slider 210 and the second slider 220 further include a connecting portion 203, through which the first portion 201 is connected to the second portion 202. The elastic member 300 also includes a second elastic member 320, which is disposed between the connecting portion 203 of the first slider 210 and the connecting portion 203 of the second slider 220. Optionally, the second elastic element 320 may be, but is not limited to, a spring. The first end of the second elastic element 320 may be connected to the connecting portion 203 of the first sliding element 210, and the second end of the second elastic element 320 may be connected to the connecting portion 203 of the second sliding element 220. During the process of the first sliding element 210 and the second sliding element 220 approaching each other, the connecting portion 203 of the first sliding element 210 and the connecting portion 203 of the second sliding element 220 directly compress the two ends of the second elastic element 320 respectively.
[0044] By adding a second elastic element 320 to the first elastic element 310, the number of elastic elements 300 increases, and the elastic force, i.e. the damping force, of the electronic device during the state switching process is further increased, which is more conducive to the electronic device maintaining a stable position at the preset angle and improving the user experience.
[0045] In an optional embodiment, the hinge mechanism S further includes a positioning post 500, located between the first rotating shaft 410 and the second rotating shaft 420. The positioning post 500 is fixed in position relative to the first rotating shaft 410 and the second rotating shaft 420. The connecting portion 203 of the first sliding member 210 and the connecting portion 203 of the second sliding member 220 are both provided with connecting holes that mate with the positioning post 500. The second elastic member 320 is sleeved on the outside of the positioning post 500. Optionally, the first end of the positioning post 500 can extend into the connecting hole of the first sliding member 210, and the second end of the positioning post 500 can extend into the connecting hole of the second sliding member 220; or, the first end of the positioning post 500 passes through the connecting hole of the first sliding member 210, and the second end of the positioning post 500 passes through the connecting hole of the second sliding member 220. Thus, by using the positioning post 500 to guide the deformation direction of the second elastic member 320, it is beneficial for the second elastic member 320 to accurately undergo elastic deformation along the axial direction of the positioning post 500.
[0046] Of course, in other embodiments, when the second elastic member 320 and the first elastic member 310 located on both sides thereare closely arranged, the possibility of the deformation direction of the second elastic member 320 being offset is small, and in this case, the positioning post 500 may not be provided.
[0047] In an optional embodiment, the axis of the positioning post 500 intersects with the first rotating shaft 410, or the axis of the positioning post 500 is parallel to the first rotating shaft 410, that is, the positioning post 500, the first rotating shaft 410, and the second rotating shaft 420 are parallel to each other. Compared with the previous embodiment, in the latter embodiment, the deformation directions of the first elastic member 310 and the second elastic member 320 are the same. In the arrangement direction of the first part 201, the connecting part 203, and the second part 202 of the first sliding member 210, the space occupied by the second elastic member 320 is smaller. Therefore, the reserved space between the two first elastic members 310 located on both sides of the second elastic member 320 can be reduced, making the structure more compact and helping to reduce the space occupied by the hinge mechanism S.
[0048] In an optional embodiment, the hinge mechanism S further includes a first bracket 610 and a second bracket 620. The first bracket 610 is located at the end of the first sliding member 210 away from the second sliding member 220, and the second bracket 620 is located at the end of the second sliding member 220 away from the first sliding member 210. The first end of the positioning post 500 is connected to the first bracket 610, and the second end of the positioning post 500 is connected to the second bracket 620. The first rotating part 110 of the rotating member 100 is engaged with the first bracket 610 at the upper limit of the axial direction of the rotating shaft 400. The connecting part 203 of the first sliding member 210 is engaged with the first bracket 610 at the upper limit of the axial direction of the positioning post 500. The second rotating part 120 of the rotating member 100 is engaged with the second bracket 620 at the upper limit of the axial direction of the rotating shaft 400. The connecting part 203 of the second sliding member 220 is engaged with the second bracket 620 at the upper limit of the axial direction of the positioning post 500. Optionally, the first rotating part 110 and the second rotating part 120 of the first rotating member 101 are respectively engaged with the first bracket 610 and the second bracket 620 at the upper limit of the axial direction of the first rotating shaft 410, and the first rotating part 110 and the second rotating part 120 of the second rotating member 102 are respectively engaged with the first bracket 610 and the second bracket 620 at the upper limit of the axial direction of the second rotating shaft 420.
[0049] In this embodiment, the first bracket 610 and the second bracket 620 respectively limit the first rotating part 110 and the second rotating part 120 of the rotating member 100, so that the rotating member 100 is kept at a certain axial position of the rotating shaft 400, and the rotating member 100 is prevented from moving axially along the rotating axis. At the same time, the first bracket 610 and the second bracket 620 respectively limit the axial position of the first sliding member 210 and the second sliding member 220 along the rotating axis, and prevent the first sliding member 210 and the second sliding member 220 from moving excessively.
[0050] Optionally, in embodiments where the hinge mechanism S includes a base 700, both the first bracket 610 and the second bracket 620 are fixedly connected to the base 700. In other embodiments, the hinge mechanism S may be provided with other limiting structures to restrict the axial positions of the rotating member 100, the first sliding member 210, and the second sliding member 220. In this case, the hinge mechanism S may not need to separately provide the first bracket 610 and the second bracket 620.
[0051] In an optional embodiment, at least one of the first bracket 610 and the second bracket 620 includes a connected limiting part 601 and a protrusion 602. The limiting part 601 is sleeved on the outside of the rotating shaft 400, and the limiting part 601 is in axial upper limit engagement with the first rotating part 110 or the second rotating part 120 of the rotating member 100. The protrusion 602 is connected to the positioning post 500, and the protrusion 602 is in axial upper limit engagement with the connecting part 203 of the positioning post 500. Optionally, the limiting portion 601 of at least one of the first bracket 610 and the second bracket 620 includes a first limiting portion 601 and a second limiting portion 601, which are respectively located on both sides of the protrusion 602. The first limiting portion 601 of the first bracket 610 and the first limiting portion 601 of the second bracket 620 are both sleeved on the outside of the first rotating shaft 410, and the second limiting portion 601 of the first bracket 610 and the second limiting portion 601 of the second bracket 620 are both sleeved on the outside of the second rotating shaft 420. The protrusion 602 may be provided with a mounting hole, and one end of the fastener passes through the mounting hole and the base 700 in sequence, which can connect the first bracket 610 and the base 700, or connect the second bracket 620 and the base 700. The fastener may be a screw or a bolt.
[0052] The first bracket 610 and the second bracket 620 are sleeved on the rotating shaft 400 through the limiting part 601 to provide support for the rotating shaft 400 and keep the rotating shaft 400 in a fixed position. At the same time, the limiting part 601 of the first bracket 610 is in limiting cooperation with the first rotating part 110, and the limiting part 601 of the second bracket 620 is in limiting cooperation with the second rotating part 120. Since the limiting part 601 is arranged around the rotating shaft 400, the limiting cooperation area is large, which is conducive to the rotating part 100 being more stably maintained in a certain axial position of the rotating shaft 400.
[0053] In the scheme of this application, the first rotating part 110 is provided with a first driving wedge surface a, and the first sliding member 210 is provided with a second driving wedge surface b. The first driving wedge surface a and the second driving wedge surface b cooperate with each other. When the first rotating part 110 rotates, it drives the first sliding member 210 to move through the first driving wedge surface a and the second driving wedge surface b; and / or, the second rotating part 120 is provided with a third driving wedge surface c, and the second sliding member 220 is provided with a fourth driving wedge surface d. The third driving wedge surface c and the fourth driving wedge surface d cooperate with each other.

[0057] By utilizing at least two first driving wedge surfaces a and at least two second driving wedge surfaces b, it is beneficial for the first rotating part 110 to stably drive the first sliding member 210 to move. Similarly, by utilizing at least two third driving wedge surfaces c and at least two fourth driving wedge surfaces d, it is beneficial for the second rotating part 120 to stably drive the second sliding member 220 to move.
[0058] In an optional embodiment, the hinge mechanism S further includes a first gear 810 and a second gear 820. The first gear 810 is sleeved on the outside of the first rotating shaft 410, and the second gear 820 is sleeved on the outside of the second rotating shaft 420. The first gear 810 and the second gear 820 can directly mesh with each other. Alternatively, the hinge mechanism S further includes one or more transmission gears 830, which are disposed between the first gear 810 and the second gear 820 and mesh with the first gear 810 and the second gear 820 respectively. In this way, the first rotating shaft 410 and the second rotating shaft 420 achieve synchronous rotation through the first gear 810 and the second gear 820. The first rotating member 101 and the second rotating member 102 also rotate synchronously, so the first housing and the second housing of the electronic device also achieve synchronous rotation, which helps to improve the state switching efficiency of the electronic device.
